RE: sorting and parameters

>How do I pass a sort key to a stylesheet?
In response to this problem and others of the same ilk, the next version of
SAXON will contain an extension function evaluate() which takes as its
argument an XPath expression in the form of a string, and returns the result
of evaluating that expression.
So you will be able to write
<xsl:param name="key">normalize-space(title)</xsl:param>
. . .
<xsl:sort select="sxf:evaluate('$key')" order="{$sortorder}"/>
